2. Verify your WhatsApp number
Alerts are delivered to the phone number you verify here. Verification uses a one-tap code sent to WhatsApp itself — no SMS fees, no extra app to install.
Step 1 — Open Phone Numbers
From the left sidebar, click Phone Numbers.
Step 2 — Click Add WhatsApp Number
You'll see an input form.
- Phone number — enter in international E.164 format, starting with
+and the country code. Examples:+34612345678(Spain)+14155552671(US)+447911123456(UK)
- Display name (optional) — a friendly label like "Personal" or "Work phone". Useful if you later add multiple numbers.
- Click Add.
Country code matters
Make sure to include the + and the country code. Numbers entered without a country code will fail.
Step 3 — Check your WhatsApp
Within a few seconds, you'll receive a message from WallaWhats containing a 6-digit verification code.
The message looks like this:
WallaWhats
123456 is your verification code. For your security, do not share this code.
[Copy code]
Tap Copy code — WhatsApp copies the digits to your clipboard automatically.
Step 4 — Enter the code
Back in the browser, enter the 6-digit code into the verification field and click Verify.
Step 5 — Confirmed
Your phone appears in the list with a green Verified badge. You can now receive alerts on this number.
Troubleshooting
I didn't receive the code.
- Check you entered the number in the correct E.164 format.
- Make sure the phone is connected to the internet and WhatsApp is installed.
- Wait up to 1 minute — delivery can occasionally be delayed during peak hours.
- Click Resend code if nothing arrives.
The code expired.
- Codes are valid for 15 minutes. If yours expired, click Resend code to get a new one.
I need to change my number.
- Delete the existing phone with the trash icon, then add a new one. Any active subscriptions tied to the old number will be paused until you re-link them.
